‘Momentum’ is a series of aerometers that give off subtle warnings if you need to improve your indoor air quality. Instead of beeping or blinking, these devices start rotating silently when they detect high levels of particulates, low humidity or low oxygen. They improve comfort and human wellbeing in more than one way; even their warning is designed not to cause any discomfort. Abstract, poetic and tranquil, their appearance reveals what they are for: a pale blue drop to indicate water, a matte black disc for particulate matter, and a white half sphere with a transparent top for ventilation. The use of Momentum in your home will give you an indoor climate that promotes health, comfort and a sense of well-being.
